CANADA THISTLE CONTROL ON ROADSIDES

THE CONTROL OF CANADA THISTLE (CIRSIUM ARVENSE, SCOP.) IS AN IMPORTANT FACET OF THE VEGETATION MAINTENANCE PROGRAM CONDUCTED BY THE MINNESOTA HIGHWAY DEPARTMENT. PICLORAM APPLIED AT 3/4 LB/ACRE REDUCED THISTLE STANDS BY 80 TO 100 PERCENT AS COMPARED TO A MAXIMUM OF 55 PERCENT ACHIEVED WITH 2, 4-D AT 4 LB/ACRE. WHERE LEGUMES CONSTITUTE A SIGNIFICANT PORTION OF THE ROADSIDE COVER PICLORAM SHOULD NOT BE USED. THE BEST TIME TO APPLY PICLORAM IS LATE SUMMER WHEN THERE IS THE LEAST DANGER OF POSSIBLE DAMAGE TO CROPS IN ADJACENT FIELDS. /BPR/
